02
Select conflict detection rules
Choose which conflict rules to enforce — exams on holidays, exam periods overlapping breaks, two simultaneous exam periods, or study periods interrupted by holidays. Toggle any rules you don't need.

Prof. Chaminda Jayawardena
Academic Registrar
*****

"We published the 2024 exam timetable with a public holiday falling on the third day of the Engineering finals — a mistake that required an emergency email to 800 students. This tool would have caught that in 10 seconds."

DF
Dilhara Fernando
Timetable Coordinator
*****

"The overlapping exam period rule is the one we use most. With 6 faculties scheduling independently, it's easy for Engineering finals to run into Business exams for shared service modules. The tool flags it before anyone notices."

NR
Nimali Rathnayake
Quality Assurance Officer
*****

"Our QA process now includes running all proposed calendars through this tool before board approval. It's become a standard step — takes 5 minutes and has prevented 3 scheduling errors in the past year."

Kasun Senanayake

"The per-event status column is exactly what I needed. When presenting the calendar to the academic committee I can show a clean table where every event is marked OK or flagged — much more credible than saying 'I checked it manually'."
